Everyone who can operate a keyboard will be able to create custom maps for id Tech 3 based games with this

The motivation behind aa2map is that reverse engineering 3D file formats and writing a program in C that generates all geometry
was much easier (for me) than understanding the proprietary knowledge behind 3D modeling software

It (still) fails at generating maps for fast-paced shooters which need a lot of fine-tuning according to the game physics and which basically
need to be designed by a human who is an artist and has a very good understanding of the gameplay

aa2map succeeds at generating maps with random structures, obstacles and defilades which work just fine for tactical shooters
